Using available volume to predict fluid diffusivity in random media
2006
Physical Review E
Preserved Fulltext
Other Versions
We propose a simple equation for predicting self-diffusivity of fluids embedded in random matrices of identical, but dynamically frozen, particles (i.e., quenched-annealed systems). ...
The only nontrivial input is the volume available to mobile particles, which also can be predicted for two common matrix types that reflect equilibrium and non-equilibrium fluid structures. ...
The Texas Advanced Computing Center ͑TACC͒ provided computational resources for this study. ...
